Application filed December 30, 1926. Serial No. 158,010.

This invention relates to a strainer and lirt collector and it is an object of the in vention to provide a device of this kind wherein air or other fluids has ettect-ively separated therefrom dirt or other foreign matter which'may be carried thereby.

It. is also an object of the invention to provide a device of this kind embodying a member through which fluid to be treated passes together with a strainer interposed in the line of travel of the fluid through the member, a part of such member constituting;

a collecting cup for dirt or other foreign matter.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved strainer and dirt collector whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood I will now proceed to describe the samev with reference to the accompanying drawing, wherein Figure 1 is a. view in side elevation of a strainer and dirt collector constructed in accordance with an embodiment of my inven tion; I

Figure 2 is a view in top plan of the device as illustrated in Figure l;

Fi re 3 is a sectional view taken substantially on the line 33 of Figure 2;

Figure 4 is a sectional view taken sub .stantially on the line H of Figure 1;

Fi ure 5 is a sectional view taken substantlally on the line 5-5 of Figure 3.

As disclosed in the accompanying drawin%, B denotes a body, preferably. cast, and so stantiallyT-shaped in elevation. This body B comprises two bores or passageways 1 eachleading from an end of the head por tion QLlofthe body and terminating atthe lower end of the stem portion 3. Each of the bores. or passageways 1 at its upper portion, or that extremity at an end of the head 2, has its walls internally threaded, as at 4, whereby the device may be readily interposed within a desired line. It is to he funderstood, however, that the body B may be coupled within a line in any other manner preferred. 1' find it of advantage to provide the head portion 2 of the body B with an arrow 5 or other indication so that it may be readily determined in which direction fluid is passing through the device ht when'in applied or working position.

The lower or free end portion of the stem '3 of the body B is provided with a circular flange 6 through which are disposed the holding bolts 7. These bolts 7 are also die5 rected through the outstanding flange 8 defining the upper end portion of the cup or bowl member G whereby the members B and Q are efiectiv'ely maintained in applied position. and G and their flanges 6 and 8 isa gasket 9 of desired material whereby leakage be tween the assembled members is prevented. This gasket 9 may be made of rubber, copper,

interposed between the. members 13 76 lead, or any material that will assure an air or watertight joint.

The upper end of the cup or bowl member 0 1s partially closed by a plate 10 integrally formed with the member and which provides a relatively large opening 11 with which the all inlet bore or uassage'way 1 communicates.

Carried by the sidewall of the member 0 and extending inwardly and downwardly thereof is a plate 12, said plate extendingentirely across the adjacent end ofthe in $5 let here or passageway l and terminating at a point inward of the plate l0 hereinbefore referred to. The plate 10 is provided with an opening 14 which registers with the outlet here or passageway 1 cit the body B.

Extending within the member it} through the opening leiis a straining element 15; This element 15 is what might be termed tunnelshaped and has its open end upwardly dis,

posed. This open end is defined by an out standingflange 16 which is received within a rabbet 17 provided in the inner end of the outlet bore or passageway 1 whereby the straining element is edectively maintained in desired position when the members B and G till ,dirt collector the member C. The fluid as it passes out through the outlet passageway or bore 1 first passes thrugh the element 15, said element 15 being of a character to substantially entirely remove from the fluid all dirt or for eign matter.

This strainer 15 will be made of such niaicrial as its particular use may prefer. When my improved device is employed in connection with the air line of an air brake equipment a screen of desired mesh sulfices although, on the other hand, if my improved device is to be used for separating dirt or foreign matter, such as water, from gasoline the straining element is of chamois. However, as I dovnot wish to limit myself to the particular or specific type of straining element it is not believed a further detailed disclosure is necessary.

While I have found my improved strainer and dirt collector can be employed to advantage in connection with water, gas, gasoline, etc., I have particularly used the same in connection with an air line of an air brake equipment. When so used I found that elfective operation or functioning of the triple valves is assured resulting in a quicker starting of the train with less chance of the train breaking in two and substantially eliminating the liability of flat wheels, hot 'ournals, damaged and pulled out draft rigging together with a material saving in fuel. These advantages can be directly attributed to the keeping of dirt and foreign matter from the triple valves.

By removin the plug 20, which can be very readily one, it is possible to determine in cold weather if the member G is clogged with ice and also provides a pronounced saving in time and labor when inspecting a frozen brake system. It is to be understood that at all times the removal of the plug 20 facilitates the cleaning out of the member O.

It is also to be particularly noted that my improved device is one wherein the strainer and the dirt collector are combined in a single unit, thus avoiding two pipe connections required on present air brake equipment. This materially reduces the cost of maintenance and at the same time reduces the risk of breakage.

From the foregoing description it is thought to be obvious that a strainer and constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be as sembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for-this reason I do not wish to be understood-as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim 1. A. combinedstrainer and dirt collector comprising a body member having disposed thcrethrough an inlet bore and an outlet bore, a cup member, means for securing the body and cup member one to the'bther, the bores of the body member being in communication with the interior of the cup member, a plate carried by a wall of the cup member and extending inwardly thereof and across the point of communication between the cup member and the inlet bore, a plate partially closing the end of the cup member immediately adjacent to the body member, said last named plate having an opening communicating with the outlet bore of the body member, and a straining element extending within the cup member throu h the opening in the last plate.
